Essential Circuit Isolation
Essential electrical loads are loads that will be powered by
the home generator. Essential loads are grouped together
and wired into the transfer switch.
TO THE INSTALLER: Consult with home generator owner(s)
to discuss their selection of "Essential Circuits".
Ensure that the total of the selected load circuits fed by this
transfer switch are within the generator's rated capacity.
The following requirements apply to this type of
isolation system:
• The automatic transfer switch is installed after the main
distribution panel.
• The automatic transfer switch has a load rating of
50 Amps. This is the maximum load rating of the total
essential load.
• All wiring must conform to national, state and
local codes.
